在RT-Thread Studio QEMU/VExpress A9双核跑内核例程thread_sample时，将线程绑定在核1上，线程不运行保持ready状态，请问如何让线程运行？

```c
/*
 * 程序清单：创建、初始化/脱离线程
 *
 * 这个例子会创建两个线程，一个动态线程，一个静态线程。
 * 静态线程在运行完毕后自动被系统脱离，动态线程一直打印计数。
 */
#include <rtthread.h>

#define THREAD_PRIORITY         25
#define THREAD_STACK_SIZE       512
#define THREAD_TIMESLICE        5

static rt_thread_t tid1 = RT_NULL;

/* 线程1的入口函数 */
static void thread1_entry(void *parameter)
{
    rt_uint32_t count = 0;
    //for (count = 0; count < 10 ; count++)
      // {
           /* 线程2打印计数值 */
           //rt_kprintf("%d   thread1 count: %d\n",rt_hw_cpu_id(), count);
       //}
    while (1)
    {
        /* 线程1采用低优先级运行，一直打印计数值 */
        rt_kprintf("%d   thread1 count: %d\n",rt_hw_cpu_id(), count ++);
        rt_thread_mdelay(500);
    }
}

        rt_thread_startup(tid1);
